A higher level of detail could be achieved by not only breaking walking links at intersections, but every time the type of pedestrian facility changed. Examples of this would include the addition of driveway crossings, commercial driveway crossings, street crossings other than main intersections and areas along roads where there were no footpaths as it was reasonable to assume pedestrians walked along these areas at different speeds than they would along a formed footpath.
District centres and business retail parks have higher pedestrian traffic volume flows than other suburban footpaths and provide important facilities for the community such as shopping, healthcare and community services. Pedestrians in these areas often use buildings, especially indoor shopping malls as thoroughfares and the addition of these to the walking network would also increase the detail of the walking network and increase the accuracy of subsequent analysis.
The development of a detailed walking network is a labour intensive process. A balance must be struck between the level of detail captured in the network and amount of time invested.
Therefore the time intensive improvements to the base walking network were only carried out for centres of high pedestrian activity in the first instance. As various study sites are examined in more detail, the level of detail of the walking network around these sites should also be increased. This will incrementally improve the quality of the walking network used in subsequent analyses.
